@lukaszlenart: Thank you very much for your response. I am not sure if
this is the same issue regarding ValueStackDataSource. I get the following
error if I call in my jasper report âAâ a subreport âBâ.
"Caused by: java.lang.ClassCastException:
org.apache.struts2.views.jasperreports.ValueStackDataSource cannot be cast to
java.util.Collection"
This errors occurs upwards struts2 version 2.3.16. Same code will be
executed without errors until struts2 core 2.3.15.3 and struts 2 Jasper Reports
Plugin version 2.3.15.3. My defined variable
â$F{maintenanceBookletItemDAOList})â is a java.util.collection.
